VB非对称加解密：用vbRichClient的cCrypt演示diffie-hellman

Current Version: 5.0.44 Version: 5.0.44 - make cCairoContext.RenderSurfaceContent aware of the current WidgetRoot-Zoom on a given Context (for better Quality) Version: 5.0.43 - new SQLite-version 3.12 - changed the built-in FastLZ-compressor to LZ4 now (for better compression, and much higher decompression-speed) Version: 5.0.42 - synchronizing of the RC5-internal cTheme-Class with the current one of the vbWidgets-Project (now supporting the Case: thmTypeProgressFace as well) Version: 5.0.41 - performance-optimization for cCollection.Prop(Key) = SomeItem (no need to scan the KeySpace twice) - new SQLite-version in vb_cairo_sqlite.dll (now at the latest release 3.11) - added support for arbitrary precision math (BigInt-support) into vb_cairo_sqlite.dll (from gmplib.org, using mini-gmp.c and mini-gmp.h over __stdcall exports) Version: 5.0.40 - enabled support for SQLites "File-URIs" in the Wrappers cConnection.CreateNewDB call (FileURIs allow to work against a single InMemory-DB across threads) Version: 5.0.39 - new SQLite-version in vb_cairo_sqlite.dll (now at the latest release 3.10.2) - fix, which deals with incorrectly set Transaction-Counters in case the SQLite-Wrappers cConnection-Obj was working in "nested Named-SavePoints-Mode" - note, that this mode is not the default on a cConnection (one has to enable this kind of transaction-support explicitely), so most Users shouldn't have been affected. Version: 5.0.38 - enhanced cWebServer about WebSocket-support ... At the Moment (to keep the BinComp) - this works only for ServerPush-scenarios, but this is IMO the most interesting case anyways. For the opposite direction (Browser sends Data to the Server), there's always the normal Ajax-POST-requests... Version: 5.0.37 - enhanced the cCSV-Class-behaviour, so that it can be used now also as a plain Line- or Word-Parser (this Class was always - and still is "huge-file-capable") Version: 5.0.36 - new version of vb_cairo_sqlite.dll (SQLite-version 3.9.0 -> the new JSON- and FTS5 features are contained and enabled) - fixed inconsistencies of cWidgetForms.WindowState at the time of reporting (and reading it) in the Resize-Events (thanks to Roberto Mior for pointing that out) Version: 5.0.35 - new version of vb_cairo_sqlite.dll (SQLite-version 3.8.11.1 - and newest libJPGturbo) - slightly better decoupled Request-Handling in cWebServer Version: 5.0.34 - increased the Max-Bytes-Volume for RPC-ClientRequest-Data from 2MB to 4MB in send-direction (in receive direction, the maximum byte-volume of the server-responses remains at 8MB) Version: 5.0.33 - changed the cRPCConnection.Connect-Method internally back to a synchronously working HostName-to-IP-resolution (also increased the Max-TimeOut-Interval of the still asynchronously working cTCPClient.GetIP method from its former 100msec to now 300msec for a little bit more breathing-space in case of stressed Windows-Domain- or Name-Servers). Version: 5.0.32 - enhanced the cUniClipBoard-class about UTF8-aware CF_HTML-readout capabilities Version: 5.0.31 - changed the ZeroChar-Termination-Detection in cFSO.ShowOpenDialog- and ShowSaveDialog from Double-ZeroChars to Single-ZeroChars - in case OFN_ALLOWMULTISELECT was *not* set (the MSDN was a bit ambigous about that - thanks to Reexre for discovering that) Version: 5.0.30 - make the (ADO-Connection based) SQLite-cConverter-Class aware of Column-Default-Values (used in JET-SQL) which define AutoTimeStamps as: Date() and Now() Version: 5.0.29 - optimizations whilst Resizing takes place (reduced rectangles for Form-Background-Painting, also spared one RePaint coming from to WM_ERASEBACKGROUND) - hardened the older ucPanel-Mode in case of Stop-Button-Presses in the VB-IDE Version: 5.0.28 - optimizations in the Form-Rendering-Engine (+ suppressing of a flickering Form-BackColor, when GPU-Surfaces are used against a Form without WidgetRoot) Version: 5.0.27 - cColumn (one of the SQLite-Classes)... fix for parsing Column-constraint-infos when intermixed with Foreign-Key-Definitions per "REFERENCES"-Keyword (thanks to Wolfgang Enzinger again, who found that and provided a Demo) Version: 5.0.26 - added four new methods to cCrypt (in addition to the MD5, SHA1 and SHA256 Methods there is now SHA384, SHA512 and their HMAC-variants as well) - internal performance-optimization when cMemDB.ExecCmd is called (using a cached CommandObject now, as long as the SQL-CommandString is not changed). Version: 5.0.25 - some enhancements in the Variant-serialization-code for RPC and Threading (support for empty (0 to -1) Arrays of all types + support for Object-serialization of cArrayList) - Thread-Events which were formerly coming in a bit "stuttering", now come in more fluently Version: 5.0.24 (including new companion-lib with SQLite-version 3.8.9) - cTable (one of the SQLite-Classes)... fix for parsing column-infos (when Primary-Key-Defs are followed by a Check-Constraint, thanks to Wolfgang Enzinger who found that) - cDirList (enhancements on the sorting-capabilities), the String-related SortOptions as: dlSortByName, dlSortByDisplayName, dlSortByExtension will now sort "logically" (similar to the the Win-Explorer) when passed as negative EnumValues (with a leading unary-minus, or using the appropriate new EnumValues: dlSortByNameLogically, dlSortByDisplayNameLogically, dlSortByExtensionLogically) - cWidgetBase... slight improvements with ToolTip-Handling, the Positioning-Event (W_ShowToolTip) is now properly raised also in case of changing a ToolTips Caption per cWidgetBase.ToolTip-Prop. - on Win7 and higher, the Surface-Uploads (in DXSurface-Mode, useful for fast, final stretching) are using Direct2D instead of DirectX now (working also within the reduced DX-capabilities of VM-Guest-OSes, thanks to Colin for the Test-Projects) - small backport-fix in the C-Sources of vb_cairo_sqlite.dll (to make cairo_in_stroke work more reliably also on non-flattened Paths (as Beziers for example). Version: 5.0.23 - completed the implementation of cVBDraw, which implements the VB.Printer-Interface and is useful when somebody wants to work with VBs old Drawing-Commands against either a Cairo-Image- or -PDF-Surface - dragging of Widgets in cWidgetRoot.DesignMode now behaving a bit more like in the VB-IDE (there's also a new Bubbling-Event "DesignDragAdjustXY" to react oneself with other coords than the defaults whilst a Widget is Moving) - added a white-ish contrasting shadow to the DragCoordsCursor-TextOut at this occasion Version: 5.0.22 - new (and much faster than e.g. the CSON-SQLite-C-Addon) JSON-serialization from SQLite-Recordsets with the new method: cRecordset.ToJSONUTF8 - fixed a misbehaviour with cWidgetForm.SetMinMaxDimensions (where dragging from Top/Left was causing a Form-Move too (switched from WM_WindowPosChanging to WM_GETMINMAXINFO to handle that problem) Version: 5.0.21 (including new companion-lib with SQLite-version 3.8.8.1) - small fix in the cConstructor.Timer construction-routine, in case one passes an Object into the Tag-Param - *new version of vb_cairo_sqlite* (now not only including QR-Decoding/Encoding-support, but also the latest SQLite-version 3.8.8.1) - please read the updated Library-Licenses for details on the quirc-lib by Daniel Beer - and for libqrencode by Kentaro Fukuchi - in short, both licenses allow commercial usage... there's new cQRDecode- as well as cQREncode-Classes in the latest GitHub-version of the vbWidgets.dll Version: 5.0.20 - enhanced cFSO.GetFileIconSurface about the capability to understand also Paths of the Form ::{GUID} ... and handing out the correct IconSurface in these cases too Version: 5.0.19 - fix in cDirList-FileWatcher-Functionality - don't throw a Dll-internal Error, when the watched directory itself gets m
